` To all 'whom it may concern.'

Be it known that' ll, JULIAN KENNEDY, a

v.citizen of thel United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful improvement in Rolling-M111 lrFables, of which the following is a full,

clear, and exact description, reference being had Ito the accompanying drawings, forming part ofthis'specifcation, in which- Figure 1 is a plan view 'of a portion of a .rolling mill table embodying my invention;

Fig. 2 is a side elevation of .the same;

Fig. 3 is a cross sectional view on the line lille-IH of Fig. 2;

f Figs. 4 and 5 are detail views of the manipulator parts showing said parts in did'erent positions; and

, Fig. 6 is a plan view of a portion of the apparatus hereinafter more particularly described.

My invention has relation to rolling mill tables, and is designed to provide a table which can be moved laterally either from one position to another of a single stand of rolls or from one stand `of rolls to another. A further object of the invention is to provide a table of this character with manipu.- lator means whereby the piece being rolled can be turned intermediate diEerent roll passes.

The nature of my invention will be best understood by reference to the accompanying drawings, in whichv l have shown the preferred embodiment thereofl and which will now be described, it being `premised, however, that various changes can be made in the details of constructlon, arrangement and combination of the several parts with vout departing -from the spirit and scope of my invention as defined inthe appended claims.

Referring to these drawings, the numeral i 2 designates thev frame of the table, in whichare journaled a plurality of'rollers 3, hav- 'ing driving gears or pinions 4, engaged by pinions 5, on the longitudinal shaft 6, which` may be driven by an electricl'motor 7 mounted on the table itself. v

rllhe numerals 3 and 9 designate fixed guides over theje'nd portions of the table rollers 3. The entire table is mounted on suitable trucks 10, adapted to travel on tracks 11, so that it may' be moved laterally ith from pass to pass of a suitable stand of rolls or from one stand of rolls to another. Forv the purpose o f thus moving the table, one of the truck axles 12 is geared, as indicated at 13 (see Fig. 3) to the armature of an electric motor 14, which is also mounted on the table.

The numeral 15 designates a manipulator -manipulator 15. 'The .tappet member has the two jaws and 26, which are adapted to be engaged bya roller 27, mounted in a fixed bracket 28 on the table, in the manner hereinafter described.

The numerals 29, 30 and 31 (see Fig. 1) designate suitable controllers for the respective electric motors, before mentioned. 'lFhe controller 31 controls the electric motor 21, which actuates the member 17. 32 is a chain or other flexible connection attached to the member 17 at one end and which passes under a suitable guide sheave or pulley 33, and thence upwardly and around a grooved wheel 34, its free end being weighted, as

indicated at 35 (see Fig. 3). The controller lever 36 has a middle position in which the motor 21 is inactive.l When moved in one direction from this middle osition, the motor is energized to actuate t e member' 17 in one direction, and when said lever is moved in the opposite direction, the motor is ener- :Zed to move the member 17 in the opposite rection. v

With the parts in the position shown in Figs. 1 and 4, the motor 21 being energized in the right direction, the train of gears 20 1s put in motion to thereby actuate the pin-- ion 19 to move the member 17 to the right. The lower arm of the manipulator 15 moves between adjacent rollers 3 underneath the piece X being rolled, until the upright arm of the manipulator contacts with said piece. At about this time, the jaw 25 of the .tappet 22 contacts with the roller 27, thereby causing` said tappet to move to an upright position, as indicated in dotted lines in Fig. 5.v

This movement of the tappet` Ithrough the link connection 24 moves the manipulator 15, first, into the position shown in dotted roo MLU

tially turning the work piece X, and finally linto the reversed position shown in full lines in Fig. o. This leaves the work piece in its turned position with the other arm of the manipulator member extending underneath it. The Work piece can then be centered with respect to the roll pass, either by moving the table bodily or by reversing the motor 21, to thereby reverse the movement of the member 17. If this reverse movement of the member 17 is stopped before the jaw 26 of the tappet 22 engages the roller 27 on the return-movement, the work piece would simply be moved laterally. When it is desired to again turn the work piece, the motor 21 is reversed and the action of the lroller 27 on the tappet 22 will-operate the tappet and the manipulator to bring the parts back to the position shown in Figs. 3 and 4. Any desired number of the manipulator members 15 may be employed throughout the length of the table. The members 17 carrying these members may be actuated in unison by a plurality of pinions on the common shaft 203.

The counterweight 35 takes up the slack in the connection 32 as the member 17 moves to the right and causes a rotation of the wheel 34:. This wheel is provided with a projection 37 (see Figs. 3 and 6) which is adapted to coperate with a projection 38 on the lever 36. If the lever 36 is moved to the left from the position shown in Fig. 3,

the motor 21 will be energized in a direction to move the member 17 to the right. This will cause the clockwise rotation of the Wheel 34, and will bring the projection 37 around into a position to contact with the projection 38 on the lever, thereby mechanivcally moving said lever back to its mid position. .When the lever is afterward moved to the right to reverse the motor, the reverse movement of the Wheel 34, due to the pull onthe chain 32, will likewise bring the projection 37 into contact with the projection 38 and move said lever back to its -mid position.

My invention provides a table for rolling mills-which is entirely self-contained, and which carries the motive power for actuating the table rollers, for moving thev table ltself and for actuating the manipulator mechanism. The table being movable laterally, the necessity for movable guides in connection with the manipulators is rendered unnecessary. By a device such as that shown and described, all that is necesf at the proper times.

I claim: 1. A rolling mill table mounted for latrecaer@ eral movement, manipulator mechanism carried thereby, and motive means carried by the table for propelling thetable and also for actuating the manipulator mechanism, substantially as described. y

2. A rolling mill table mounted for lateral movement and having a series of table rollers, manipulator mechanism mounted on the table,l and motive means carried by the table for moving the table laterally for rotating the table rollers and for actuating the 'manipulator mechanism, substantially as described.

3. A rolling mill table having a carriage mounted to move transversely thereon, a manipulator member pivoted to the carriage, said member having two arms at substantially right angles to each other, means for actuating said carriage to move said member laterally, and means whereby the said member may be turned on its pivot through an angle of substantially ninety degrees, at the completion of its lateral movement, substantially as described.

Ll. A rolling mill table having fixed longitudinal guides, a carriage mounted for transverse movement on said table, a manipulator member pivoted to said carriage, said member having a portion adapted to engage and slide a work-piece laterally on the table and another portion adapted to have a turning engagement with the work-piece, and means actuated by the movement of the carriage for turning said member on its pivot after it has moved the work-piece laterally, 100 substantially as described.

5. A rollingmill table having a carriage mounted to move transversely thereon, a manipulator member pivoted to the carriage,

a tappet member also pivoted to the carriage 105 and connected with said manipulator, and a relatively fixed member arranged to be engaged by the tappet member at a certain point in the movement of the carriage to thereby effect a pivotal movement of the maating connection between the tappet device and the manipulator member, and relatively fixed means on the table for coperation with the tappet device, substantially as described. ,n sary to actuate the manipulators is for the 7. In a rolling mill table, the combination with a transversely movable manipulator device, of a motor for actuating said device, a controller for said motor, and means actuated by the movement of said device for returning the controller to inoperative position, substantially as described.

8. In' a rolling mill table, the combina- 130 mamar tion of a transversely movable carriage, a manipulator device on said carriage, a motor for actuating the carriage, a controller for the motor having an actuating lever, and means operated by the movement of the carriagefor returning said lever to its initialposition after operation, substantially as described.

9. In a rolling mill table, the combination with a transversely movable carriage having a manipulator device thereon, a motor for v actuating theI carriage, a controller for said motor, said controller having a control lever mounted for movement in both directions from a central neutral positlon, and means 155 actuated by the movement of said carriage' for returning said lever to its neutral position after movement in either direction,`sub stantially as described.

In testimony whereof, I have hereunto set 2n,

MARGERY FITZGERALD.
